解析从INI配置文件读取到操作命令

2009年2月23日星期一

由于工作中遇到文件更新到开发，自然涉及到从配置文件中读取操作命令，以便中更新过程中进行操作。下面以工作中的Demo为示例：

[Setting]

Version=1.2.3.0

[Files]

umini_console.exe={desktop}

install_driver.exe={thisdir}

umini_ocx.ocx={thisdir}/..

umini_info.info={system32}/TS_Info

[ AfterUpdate]

RegFile={thisdir}/../umini_ocx.ocx

Execute={thisdir}/ install_driver.exe –i

DeleteFile={thisdir}/ install_driver.exe

RegEdit=HKEY_LOCAL_MACHINE;SOFTWARE/UMINI/ KeyLogon;Rules;REG_DWORD;1

 

这里我不讲怎样读取配置文件，主要说下怎么样通过从配置文件中读取到到参数进行解析。主要涉及两个参数：KeyName和KeyValue，KeyName可以取值RegFile/Excute/DeleteFile…，KeyValue可以取值{thisdir}/../umini_ocx.ocx。具体不再讲解，下面给出详细源码：

BOOL ExcuteINIOrder(LPCTSTR szKeyName, LPCTSTR szKeyValue)

{

     // Explain the order

     CString strValue,strKeyValue(szKeyValue);

     strKeyValue.Remove(' ');

     TCHAR szTemp[MAX_PATH];

     if (0 == strKeyValue.Find(_T("{thisdir}")))

     {

         // {thisdir}

         CString strDir(_T("{thisdir}"));

         strValue = strKeyValue.Right(strKeyValue.GetLength() - strDir.GetLength());

 

         // Get Current dir

         strValue = _T(".") + strValue;

     }

     else if (0 == strKeyValue.Find(_T("{desktop}")))

     {

         // {desktop}

         CString strDir(_T("{desktop}"));

         strValue = strKeyValue.Right(strKeyValue.GetLength() - strDir.GetLength());

 

         // Get Desktop

         ::SHGetSpecialFolderPath(NULL,szTemp,CSIDL_COMMON_DESKTOPDIRECTORY,FALSE);

         CString strTemp(szTemp);

         strValue = strTemp + _T("//") + strValue;

     }

     else if (0 == strKeyValue.Find(_T("{system32}")))

     {

         // {system32}

         CString strDir(_T("{system32}"));

          strValue = strKeyValue.Right(strKeyValue.GetLength() - strDir.GetLength());

 

         // Get System32

         ::SHGetSpecialFolderPath(NULL,szTemp,CSIDL_SYSTEM,FALSE);

         CString strTemp(szTemp);

         strValue = strTemp + _T("//") + strValue;

     }

     else if (0 == strKeyValue.Find(_T("{sysdriver}")))

     {

         // {sysdriver}

         CString strDir(_T("{sysdriver}"));

         strValue = strKeyValue.Right(strKeyValue.GetLength() - strDir.GetLength());

 

         // Get Sysdriver

         ::SHGetSpecialFolderPath(NULL,szTemp,CSIDL_SYSTEM,FALSE);

         CString strTemp(szTemp);

         strValue = strTemp + _T("//") + strValue;

     }

     else if (0 == strKeyValue.Find(_T("{startup}")))

     {

         // {startup}

         CString strDir(_T("{startup}"));

         strValue = strKeyValue.Right(strKeyValue.GetLength() - strDir.GetLength());

 

         // Get Startup

         ::SHGetSpecialFolderPath(NULL,szTemp,CSIDL_STARTUP,FALSE);

         CString strTemp(szTemp);

         strValue = strTemp + _T("//") + strValue;

     }

 

     // Excute the order

     if (0 == _tcscmp(szKeyName,_T("Execute")))

     {

         // Excute

          SHELLEXECUTEINFO ShExecInfo = {0};

         ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);

         ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;

         ShExecInfo.hwnd = NULL;

         ShExecInfo.lpVerb = NULL;

         ShExecInfo.lpFile = strValue;       

         ShExecInfo.lpParameters = _T("");   

          ShExecInfo.lpDirectory = _T("");

         ShExecInfo.nShow = SW_SHOW;

         ShExecInfo.hInstApp = NULL;

         ShellExecuteEx(&ShExecInfo);

         DWORD dw = GetLastError();

         WaitForSingleObject(ShExecInfo.hProcess,INFINITE);

     }

     else if (0 == _tcscmp(szKeyName,_T("DeleteFile")))

     {

         // DeleteFile

         ::DeleteFile(strValue);

     }

     else if (0 == _tcscmp(szKeyName,_T("RegFile")))

     {

         // RegFile

         RegisterOcx(strValue);

     }

     else if (0 == _tcscmp(szKeyName,_T("UnRegFile")))

     {

         // UnRegFile

         UnRegisterOcx(strValue);

     }

     else if (0 == _tcscmp(szKeyName,_T("RegEdit")))

     {

         // RegEdit

         CString strKey, strSubKey, strSubKeyName, strKeyType, strSubKeyValue, strTmp;

         int i = strKeyValue.FindOneOf(_T(";"));

         strKey = strKeyValue.Left(i);

         strTmp = strKeyValue.Right(strKeyValue.GetLength() - i - 1);

         i = strTmp.FindOneOf(_T(";"));

         strSubKey = strTmp.Left(i);

         strTmp = strTmp.Right(strTmp.GetLength() - i - 1);

         i = strTmp.FindOneOf(_T(";"));

         strSubKeyName = strTmp.Left(i);

         strTmp = strTmp.Right(strTmp.GetLength() - i - 1);

         i = strTmp.FindOneOf(_T(";"));

         strKeyType = strTmp.Left(i);

         strSubKeyValue = strTmp.Right(strTmp.GetLength() - i - 1);

 

         HKEY hKey;

         if (0 == _tcscmp(strKey.GetBuffer(),_T("HKEY_CLASSES_ROOT")))

         {

              strKey.ReleaseBuffer();

              hKey = HKEY_CLASSES_ROOT;

         }

         else if (0 == _tcscmp(strKey.GetBuffer(),_T("HKEY_CURRENT_CONFIG")))

         {

              strKey.ReleaseBuffer();

              hKey = HKEY_CURRENT_CONFIG;

         }

         else if (0 == _tcscmp(strKey.GetBuffer(),_T("HKEY_CURRENT_USER")))

         {

              strKey.ReleaseBuffer();

              hKey = HKEY_CURRENT_USER;

         }

         else if (0 == _tcscmp(strKey.GetBuffer(),_T("HKEY_LOCAL_MACHINE")))

         {

              strKey.ReleaseBuffer();

              hKey = HKEY_LOCAL_MACHINE;

         }

         else if (0 == _tcscmp(strKey.GetBuffer(),_T("HKEY_USERS")))

         {

              strKey.ReleaseBuffer();

              hKey = HKEY_USERS;

         }

 

         HKEY hRetKey;

         if (ERROR_SUCCESS != RegCreateKey(hKey,strSubKey.GetBuffer(),&hRetKey))

         {

              strSubKey.ReleaseBuffer();

              return FALSE;

         }

         strSubKey.ReleaseBuffer();

 

         // Edit

         int nSubKeyValue = _ttoi(strSubKeyValue.GetBuffer());

         strSubKeyValue.ReleaseBuffer();

         if (ERROR_SUCCESS == RegSetValueEx(hRetKey,strSubKeyName.GetBuffer(),NULL,REG_DWORD,

              (const BYTE *)&nSubKeyValue,sizeof(nSubKeyValue)))

         {

              strSubKeyName.ReleaseBuffer();

              RegCloseKey(hRetKey);

              return TRUE;

         }

         else

         {

              strSubKeyName.ReleaseBuffer();

              RegCloseKey(hRetKey);

              return FALSE;

         }

     }

     else if (0 == _tcscmp(szKeyName,_T("RegDel")))

     {

         // RegDel

         CString strKey, strSubKey, strTmp;

         int i = strKeyValue.FindOneOf(_T(";"));

         strKey = strKeyValue.Left(i);

         strTmp = strKeyValue.Right(strKeyValue.GetLength() - i - 1);

         int j = strTmp.FindOneOf(_T(";"));

         strSubKey = strTmp.Left(j);

 

         HKEY hKey;

         if (0 == _tcscmp(strKey.GetBuffer(),_T("HKEY_CLASSES_ROOT")))

         {

              strKey.ReleaseBuffer();

              hKey = HKEY_CLASSES_ROOT;

         }

         else if (0 == _tcscmp(strKey.GetBuffer(),_T("HKEY_CURRENT_CONFIG")))

         {

              strKey.ReleaseBuffer();

              hKey = HKEY_CURRENT_CONFIG;

         }

         else if (0 == _tcscmp(strKey.GetBuffer(),_T("HKEY_CURRENT_USER")))

         {

              strKey.ReleaseBuffer();

              hKey = HKEY_CURRENT_USER;

         }

         else if (0 == _tcscmp(strKey.GetBuffer(),_T("HKEY_LOCAL_MACHINE")))

         {

              strKey.ReleaseBuffer();

              hKey = HKEY_LOCAL_MACHINE;

          }

         else if (0 == _tcscmp(strKey.GetBuffer(),_T("HKEY_USERS")))

         {

              strKey.ReleaseBuffer();

              hKey = HKEY_USERS;

         }

 

         if (ERROR_SUCCESS == SHDeleteKey(hKey,strSubKey.GetBuffer()))

         {

              strSubKey.ReleaseBuffer();

              return TRUE;

         }

         else

         {

              strSubKey.ReleaseBuffer();

              return FALSE;

         }

     }

     return FALSE;

}

 

其中用到到两个函数：RegisterOcx和UnRegisterOcx来自网上（详细网址已经记不清了），下面也给出源码：

BOOL RegisterOcx(LPCTSTR OcxFileName)

 

{

 

         LPCTSTR pszDllName = OcxFileName ;         //ActiveX控件的路径及文件名       

 

         HINSTANCE hLib = LoadLibrary(pszDllName); //装载ActiveX控件

 

         if (hLib < (HINSTANCE)HINSTANCE_ERROR)

 

         {

 

                   return FALSE ;

 

         }

 

         FARPROC lpDllEntryPoint;

 

         lpDllEntryPoint = GetProcAddress(hLib,"DllRegisterServer");   //获取注册函数DllRegisterServer地址

 

 

 

         if(lpDllEntryPoint!=NULL)   //调用注册函数DllRegisterServer

 

         {

 

                  if(FAILED((*lpDllEntryPoint)()))

 

                   {

 

                            FreeLibrary(hLib);

 

                            return FALSE ;

 

                    }

 

                   return TRUE ;

 

         }

 

         else

 

                   return FALSE ;

 

}

 

 

 

BOOL UnRegisterOcx(LPCTSTR OcxFileName)

 

{

 

         LPCTSTR pszDllName = OcxFileName ;         //ActiveX控件的路径及文件名       

 

         HINSTANCE hLib = LoadLibrary(pszDllName); //装载ActiveX控件

 

         if (hLib < (HINSTANCE)HINSTANCE_ERROR)

 

         {

 

                   return FALSE ;

 

         }

 

         FARPROC lpDllEntryPoint;

 

         lpDllEntryPoint = GetProcAddress(hLib,"DllUnregisterServer");        //获取注册函数DllUnregisterServer地址

 

 

 

         if(lpDllEntryPoint!=NULL)   //调用注册函数DllUnregisterServer

 

         {

 

                  if(FAILED((*lpDllEntryPoint)()))

 

                   {

 

                            FreeLibrary(hLib);

 

                            return FALSE ;

 

                    }

 

                   return TRUE ;

 

         }

 

         else

 

                   return FALSE ;

 

}
